PRODUCT DESCRIPTION

The AS432 is a 3-terminal Adjustable Shunt Voltage Regulator providing a highly accurate 1.24V bandgap reference with 0.5%

tolerance. The AS432 thermal stability, wide operating current (80mA) and temperature range (0°C to 105°C) makes it suitable for

abroad range of applications. AS432 tolerance of 0.5% is proven to be sufficient to overcome other errors in the system to

virtually eliminate the need for trimming in the power supply manufactures assembly line and contribute a significant cost

savings.

The AS432 is an ideal voltage reference in an isolated feedback circuit for 3.0V to 3.3V switching mode power supplies. AS432

offers many advantages over TLV431, such as, wider output voltage up to 18V vs. 6V, output current of 80mA vs. 15mA, and a wider

temperature range with tighter tolerance down to 0.5%.
